2 Claims.

Our invention relates to heaters and more particularly to oil heaters.

One of the principal objects of our invention is to provide -a heater wherein, through the use of oil as fuel, air passing through the heater will be subjected to maximum radiating surface for heating thereof in a minimum period of time and with the least possible fuel consumption, the heater in its entirety being of novel construction.

Another object of our invention is to provide a heater oi the above described character which is simple in construction, durable in use, emcient in operation and economical in manufacture.

Other objects and advantages will be apparent Subjacent vthe top wall I1, the inner shell is providedv with a plurality of inclined air tubes 22 extending upwardly and forwardly with respect to the outer shell and having front and rear open ends communicating with the passage I4 as clearly illustrated in Figure 1 of the drawing.` The rear wall 9 of the outer shell has mounted thereon, rearwardly of the open ends of the tubes 22 and within the passage Il, a fan 23, the latter being equipped with an electric motor 24 for operating said fan. Air openings are arranged in the rear wall postjacent the fan blades for eilecting circulation of air through the tubes 22. Prejacent the front ends oi' the tubes 22, the

It is therefore to be understood that the invention is not limited to the specific construction as illustrated and described, as the same is only illustrative of the principles of operation, which are capable of extended application in various forms, and that the invention comprehends all construction within the scope oi' the appended claims. A

What we claim is:

1. A heater of the character described comprising a rectangular shaped casing shell having inlet apertures in the bottom and outlet slots in the top thereof, a second rectangular shaped shell mounted within the casing shell having the top, bottom and side walls spaced from the casing shell to form a heating chamber, an outlet pipe connected to the top oi' the inner shell and extending through an opening in the casing shell for the discharge of heated air and gases from the heating chamber, a plurality of air conducting tubes mounted in inclined position in the upper portion of the heating chamber and opening into the passages formed between the front and rear walls of the said shells, the said tubes being disposed so that their rear inlet ends are at a medial point with reference to the height of the casing shell while their forward outlet ends are in a position adjacent the top of the said casing shell, the said casing shell having air inlet openings in the rear wall in horizontal registration with the inlet ends ot the tubes and having outlet openings in the front wall in registration with the outlet ends of the tubes, a motor driven blower fan mounted vertically in the rear passage between the shells in position to force air through the tubes from the rear wall inlet openings and the rear passage, and means mounted within the lower portion of the heating chamber for heating the air circulating through the said tubes, the said heating chamber having air inlet apertures in the lower portions of opposed side walls thereof.

2. A heater of the character described comprising a rectangular shaped casing shell having inlet apertures in the bottom and outlet slots in the top thereof, a second rectangular shaped shell mounted within the casing shell having the top, bottom and side walls spaced from the casing shell to form a heating chamber, an outlet pipe connected to the top of the inner shell and extending through an opening in the casing shell for the discharge of heated air and gases from the heating chamber.- a plurality of air conducting tubes mounted in inclined position in the upper portion oi' the heating chamber and opening into the passages formed between the front and rear walls of the said shells, the said tubes being disposed so that their rear inlet ends are at a medial point with reference to the height of the casing shell while their forward outlet ends are in a position adjacent the top of the said casing shell, the said casing shell having air inlet openings in the rear wall in horizontal registration with the inlet ends of the tubes and having outlet openings in the front wall in registration with the outlet ends of the tubes, a motor driven blower fan mounted vertically in the rear passage between the shells in position to force air through the tubes from the rear wall inlet openings and the rear passage, and a plurality oi.' oil burners mounted in the lower portion of the heating chamber below the tubes for heating the tubes and the air circulating therethrough, the said heating chamber having louver openings in the lower portions of its opposed side walls for feeding air into the heating chamber and having bailies disposed inwardly oi' the louver apertures to deflect the air entering therethrough from the burners.
